Abstract: Junction box for connecting a multi-wire flat cable to several terminals of a connection. The junction box comprises a support surface for a multi-wire flat cable to be contacted, and several contact blades for contacting the cable on one side without stripping the insulation. In addition, the junction box comprises several terminals, and several terminal rails adjoining the terminals, wherein each terminal rail has at least one hole, wherein a contact pin is inserted through a respective hole in a terminal rail. In each case, a contact pin is provided for a wire-to-terminal contact. The assignment of contact pins to the holes in the terminal rails defines which wire of the flat cable is connected to which terminal. An electrical contact is established between contact blades and terminal rails via one or more contact pins.
